If you think starting a new job using someone else's equipment, in
a position that didn't exist previously, won't take acclimation
time, I wish you well in the world.

Light is not the only thing a photographer has to deal with,
unfortunately.

Every day professional photographers travel all over the world
using whatever rental equipment available, using makeshift studios,
jerry-rigging equipment. The OP is looking for a professional
photographer, not a jobber with a camera.
I have been doing well all over the world, thanks.

I have been on both sides of the corporate deal, and I can tell you, that 99% of the time, it is easier as a freelancer, because once you get the job, all you have to do is shoot with gear you already own. When you work for a company, you've got a constant gunfight about what equipment is needed and how badly, as a start. You most decidedly do NOT run your own show after which you bill the client for the rentals. You have to deal with permissions, just to start.

When the idea for setting up a position is to save money, you can almost always bet that the penny shaving will continue and will affect the final product.
